摘要：
This invention relates to laying nest having a rack drive expulsion system. As disclosed herein, the invention preferably comprises a laying nest for hens comprising a box and a rack drive floor expulsion system. The floor pivotably moves between first and second positions by virtue of a gear rack that is fixedly connected to and disposed within the box, and a gear wheel that is rotatably connected to the floor. Accordingly, the expulsion system provides for the selected removal of hens from the laying nests as desired.
